brain 2
| Question | Answer |
|---|---|
| Pons | inferior to midbrain; regulates movement, breathing, reflexes, and complex functions associated with sleep and arousal |
| Corpus Callosum | he largest commissural fibers that connects the right and left hemispheres |
| Fornix | c-shaped ring of white matter; main output tract |
| Medulla Oblongata | most inferior structure of the brainstem; continuous with spinal cord at foramen magnum |
| Thalamus | main entry route of sensory data into cerebral cortex; relay station that receives input, integrate info, then send info to specific motor or sensory areas in cerebral cortex |
| Choroid Plexus | where majority of CSF is manufactured; found in each of the four ventricles where blood vessels come into direct contact with ependymal cells (also produce some CSF themselves) |
| Hypothalamus | collection of nuclei anterior and inferior to larger thalamus; regulates the autonomic nervous system, sleep/wake cycle, thirst and hunger, and body temp. |
| Arbor Vitae | cerebellar cortex is extremely folded and has branching white matter that resembles tree branches |
| Lateral Ventricles | cavity that is continuous with central canal of spinal cord; lined with ependymal cells; filled with cerebrospinal fluid |
| Spinal Cord | nervous tissue that is a relay station and a processing station |
| Pineal Gland | endocrine organ that resembles a pine cone; it secretes melatonin |
| Fourth Ventricle | between pons and cerebellum; connected to 3rd ventricle by cerebral aqueduct (small passageway through midbrain) |
| Mammillary Body | receives input from the hippocampus; plays a role in memory and behavior |
